Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A device comprising: a transceiver that transmits and receives using a plurality of communication bands; an auxiliary receiver that communicates using a first communication band of the plurality of communication bands when the auxiliary receiver is selectively activated; a data storage structure that stores data indicating operational capabilities of the transceiver, the operational capabilities comprising a set of communication bands of the plurality of communication bands on which the transceiver communicates when the auxiliary receiver is selectively activated; and a controller that controls operation of the transceiver by selecting a communication band from the set of communication bands based on the data in the data storage structure when the auxiliary receiver is activated, wherein the transceiver communicates using an initial communication band of the plurality of communication bands when the auxiliary receiver is not activated, and wherein the controller alters the initial communication band on which the transceiver communicates if the initial communication band is not one of the set of communication bands when the auxiliary receiver is activated.
A wireless device has a primary transceiver for cellular communication and an auxiliary receiver (like for GPS or TV). The transceiver uses multiple frequency bands. When the auxiliary receiver is on, the device switches the transceiver to use only a specific, pre-defined set of frequency bands that won't interfere with the auxiliary receiver. These allowed bands are stored in memory. If the current band isn't in that allowed set, the device changes to one that is. When the auxiliary receiver is off, the transceiver can use any of its bands.
2. The device in claim 1 , wherein the controller further causes a re-registration process upon alteration of the initial communication band on which the transceiver is communicating.
The wireless device described above, when changing the transceiver's frequency band due to the auxiliary receiver being activated, also performs a re-registration process with the cellular network. This ensures the network knows the device's new frequency band and can communicate with it correctly after the band change.
3. The device in claim 1 , wherein the auxiliary receiver is part of an auxiliary transceiver.
The wireless device described above has an auxiliary receiver which is actually part of an auxiliary transceiver that has both a transmitter and receiver.
4. The device in claim 1 , wherein the data storage structure stores data relating to operational capabilities comprising a signaling protocol, a transmission power level, and a bandwidth.
The wireless device described above stores data defining the transceiver's allowed operational parameters (for interference avoidance). This data includes not only the allowed frequency bands, but also the signaling protocol (e.g., which version of a cellular standard to use), the maximum transmission power level, and the bandwidth to be used by the transceiver.
5. The device in claim 1 , wherein the auxiliary receiver is contained within a housing containing the transceiver.
The wireless device described above contains both the primary transceiver and the auxiliary receiver are located together within a single housing or physical case.
6. The device in claim 1 , wherein the auxiliary receiver receives signals from a global positioning system satellite.
The wireless device described above has an auxiliary receiver that specifically receives signals from global positioning system (GPS) satellites.
7. A method comprising: determining, by a wireless communication device comprising a processor and a transceiver, that an auxiliary receiver of the wireless communication device has been activated, wherein the transceiver communicates using a plurality of communication bands, and wherein the transceiver comprises a first transmitter and a first receiver; determining, by the wireless communication device, that the wireless communication device is not communicating on any of a set of communication bands of the plurality of communication bands on which the wireless communication device communicates when the auxiliary receiver is activated; altering, by the wireless communication device, operation of the wireless communication device to communicate using one of the set of communication bands; and re-registering, by the wireless communication device, the wireless communication device with a communications network using the one of the set of communication bands.
A wireless device with a cellular transceiver and an auxiliary receiver (like for GPS or TV) does the following: First, it detects when the auxiliary receiver is turned on. Then, it checks if the cellular transceiver is using one of the allowed frequency bands that won't interfere with the auxiliary receiver. If it's not using an allowed band, the device changes the cellular transceiver to use one of those allowed bands. Finally, the device re-registers with the cellular network using the newly selected allowed band.
8. The method in claim 7 , wherein the auxiliary receiver comprises a broadcast television receiver.
In the method described above, the auxiliary receiver is a broadcast television receiver. The wireless device switches frequency bands to avoid interference with receiving TV signals.
9. The method in claim 7 , further comprising determining that the auxiliary receiver is deactivated.
The method described above also includes detecting when the auxiliary receiver is turned off.
10. The method in claim 9 , further comprising altering operation of the wireless communication device to communicate using the one of the set of communication bands.
The method described above includes detecting when the auxiliary receiver is turned off, and then changing the operation of the wireless communication device to communicate using one of the plurality of communication bands.
11. The method in claim 7 , wherein the auxiliary receiver comprises a global positioning system receiver.
In the method described above, the auxiliary receiver is a global positioning system (GPS) receiver. The device switches frequency bands to avoid interference with GPS signal reception.
12. The method in claim 7 , wherein the auxiliary receiver is used to support network-assisted global positioning system functionality.
In the method described above, the auxiliary receiver (GPS) is used to support network-assisted global positioning system (A-GPS) functionality, where the network provides assistance data to improve GPS performance.
13. The method in claim 7 , further comprising transmitting, to the communications network, data indicating operational capabilities of the transceiver, the data comprising the one of the set of communication bands on which the transceiver operates.
In the method described above, the wireless device transmits data to the communications network indicating the transceiver's operational capabilities. This data includes the allowed frequency band that the transceiver will use when the auxiliary receiver is active.
14. A non-transitory computer-readable medium having computer instructions stored thereon that, when executed by a processor, causes the processor to perform operations comprising: determining that an auxiliary receiver of a wireless communication device that communicates using a plurality of communication bands is activated, wherein the wireless communication device comprises a transceiver, and wherein the transceiver comprises a first transmitter and a first receiver; determining that the wireless communication device is not communicating on any of a set of communication bands of the plurality of communication bands on which the wireless communication device communicates when the auxiliary receiver is activated; altering operation of the wireless communication device to communicate using one of the set of communication bands; and re-registering the wireless communication device with a communications network using the one of the set of communication bands.
A computer-readable medium stores instructions that, when executed, cause a wireless device to: detect when its auxiliary receiver (like for GPS or TV) is turned on; determine if the cellular transceiver is using one of the allowed frequency bands that won't interfere with the auxiliary receiver; change the cellular transceiver to use one of the allowed bands if it's not already using one; and re-register with the cellular network using that allowed band.
